Yeah, I’ll ask. What do you mean by swap? Several years ago I seem to recall Sun/Oracle announced that RAM now counted as swap for some reason. This messes with my head because swapping to physical memory is crazy talk. (Note that I have used some system that had DRAM that wasn’t directly addressable by the CPU and so that counted as secondary storage implemented with DRAM rather than physical memory). When Solaris derived systems talk about swap reservations is that actually _exactly_ the opposite of the virtual memory overcommit that occasionally troubles Linux systems and so swap reservation is really a virtual memory reservation?
